COIN-SELECTIN G MECHANISM.

Application flied February 4, 1926, Serial No. 8,685. Renewed May 19,1928.

This invention relates to selective mechanism for the delivery ofdesignated coins,

coin guide hung upon an inclined frame.

capable of being swung and displaced by the action of a coin or otherdevice passingthrough the coin slot; also a weighted shield that is hungupon lugs extended from the guide, which shield closes against the guideto retain the coins or spurious coins'laterally in their passage, butsaid shield bein g adapted to become separated from the guide to permitrejection of a spurious coin when another coin is entered through theslot;

form of a magnet, to engage magnetically the disks, said device havingone longer arm that projects from the frame into the path of the coinsand spurious coins, said device having a shorter arm which impales awasher whose weight is imposed on the longer arm; also a guide channelto direct true coins along a predetermined path when the weight of suchcoins is imposed upon the longer arm of the pivoted device to depressit.

Other features and advantages of my invention will hereinafter appear.

- In the drawing:

Fig. 5" is a side view thereof, and

Fig. .6 is a detail side view of the eccentrically pivoted device, inthe form of a magnet, which serves to reject all kinds of spurious coinsand permits the free passage of true or designated coins only.

In the representation of my invention herein illustrated let 1 indicatea frame upon which the mechanism is mounted, 2 an element composed ofsheet material which I call the coin 'guide, 3 another element which Icall the shield, and 4 that part of a coin box having the coin receivingslot 5. The frame 1 is disposed in an inclined position 'b'eneath theslot 5. Said frame has a rounded edge 6 to support, the guide 2 bymeans" of lugs *7 that extend rearwardly from said guide and have curvedengagi ng surfaces8, wherebysaid guide may be "swung, using said frameedge 6 as a fulcrum. -The upper end of guide 2 is pro- 7 'vided' with.an inclined nose-piece 9,"that extends up nearly to the slot 5 to be inthat a passingcoin will fall upon the incline of said nose;- iece 9, andby;its weight, so or with theadditionof pressure will cause the upper'partof the guide to..swing rearwardly upon its' fulcrnm,-thusalsocausing 'ide to swing forwardly. The coin having displaced nose- 86piece 9 will'slide down the guideagainst the forward surface thereof,said guide, due

to the preponderance .ofiit safweightbelow the .fulcrum swin ing baoltto. its normal position against t e frame, The guide is 90 providedwith sidewalls having. suitable curvatures which direct the, ath of thecoin. Thus there is .a curved wa 1 portion -10 at one side that deflectsthe coin-to the opposite side, where it meets a curved wall portion 11that deflects it back to a curved wall (portion 12, these deflectionstending to retar the speed of descent, and the curved wall portion12.-guiding the coinlaterally toward an opposite, downwardly curved wallportion 13, which .continues into a downwardly directed exit for thedelivery of the coin into an opposed passage, chute or receptacle 14. Itis the purpose of my invention that true or designated coins shall takethe course described, In their passage along the guide however, saidcoins will alight upon an arm 15 of a plate or body 16 which is pivotedat 17 to a lug 18 extended rearwardly from frame 1, said body havinganother, shorter arm 19 and constituting a magnet of which the arms 15,19 are the respective poles. The pivot 17 is so located, at the lowerpart of body 16, that the arms tend to swing upwardly, but are heldhorizontal by reason of arm 15 engaging the lower edge of frame 1, saidarm 15 being extended forwardly in advance of the front surface of theframe. The arm 19, which is shorter is entered into a slot 20 throughthe frame, its end being normally flush with the forward surface of thecoin guide, which is slotted at 2 to receive it, but capable ofprojecting beyond said surface if the device be rock-ed upon its pivot.

When a true or designated coin passes in the manner already describedalong the guide, and alights upon arm 15, the weight of such coindepresses arm 15, rocking the device upon pivot 17, and the degree ofthat depression is sufficient to provide a clearance between arm 15 andwall portion 13 to permit the coin to pass; whereas if the arm were heldrigid the coin would become wedged between it and wall portion 13. This15 what occurs to a disk or light weight coin that fails to depress arm15.

It-will be noted that the u er part of shield 3 is provided with si elugs 21, adapted to engage in bearing slots 22 formed in brackets 23that project forwardly from guide 2; also that shield 3 has a curvedlower portion 23 that lies over the laterally fxtended portion of thecoin guide-way, said ower norma y hold assing coins and spurious coinsagainst t e guide. When, however,

the uide is swung upon its fulcrum, as by t e previously described actin introducin a coin through slot 5, the shield is sprea :1 art from theguide by reason of rearwar y projecting lugs 25 on the shield which enage the frame 1 as the top part of the shiel swings backwardly.

In the tilting of guide 2 and the spreading apart action of shield 3 alightweight disk or spurious coin that may have become lodged upon arm15, thus being removed disk,

ortion being weighted, as at 24, to-

a magnet will attract and hold a magnetizable disk that reaches the arm15, preventing it from following further along the path of a true coin,and such magnetizable disk will be ejected by tilting action of theguide.

It must be appreciated that coincident with the tilting and ejectionaction of guide 2, shield 3 is spread apart therefrom to facilitate theget-away of the ejected spurious coin, disk or washer.

Limiting means to the extent of the guide tilting and shield spacingmovements are provided in the form of a lug 26 extended from the guidewall 12, in parallelism with the guide surface, said lug serving as astop to engage the shield, which in turn prevents further forwardmovement of the shield.

In Fig. 2 I have shown a true coin 27 as falling through the chute 14,and a spuri- I ous coin 28 as ejected to be guided by wall 29 into areceptacle therefor.

Also I have shown a spurious coin 30 lodged upon arm 15.

As a washer the spurious coin appears impaled upon the rojected arm 19,and if a magnetizable dis t, then it is held by the poles 15 and 19 ofthe magnet.

Variations within the spirit and scope of my invention are equallycomprehended by the foregoing disclosure.

I claim.
